Our 4cyl diesel Jeep Liberty pulled a very similar sized trailer through the black hills just fine, plenty of power and control. She got a bit warm going up a few sustained grades, had to back off the throttle a bit, but we were still easily overtaking semis, some of them were going quite slow by the top.
We recently upgraded tow vehicles to a Duramax Chevy 2500HD, but not for lack of power or control, we just want something easier to service, and we do have future plans for a larger camper, which the Jeep just would not accommodate.
